She has a rule that I have to let her know when I'm coming to her business.
Then she should respect you with the same action.
Try to be as pleasant as you can, for MIL's sake. No sense in getting her upset at you right before leaving. Use it as opportunities to show your charming personality. Just don't get all confused by any responses or reactions from your W. A lot of men allow their emotions to play havoc if the W acts nice to them. Don't make it out to be more than it is.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
